SEGIFICATION forming part of Letters Patent No. 733,750, dated July 14, 190131 Application filed April 17,1899. Serial No. 713,227. (No model.)

To all whom, t may concern;

Be it-known that I, CHARLES A. REINERS, a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Signaling Apparatus for Elevator-Cars, of which the following is hereby declared to be a full, clear, and exact description.

This invention relates more particularly to 1o that class of signaling apparatus for elevatorcars in which an electric signal (usually an incandescent lamp within the elevator-car) is controlled by the operation of push-buttons or like circuitcontrolling mechanism upon I5 the several floors of the building through which the elevator-car passes.

The invention consists in thc varousfeatures of improvement hereinafter described, illustrated in the accompanying drawings,

zo and particularly defined in the claims at the end of this specication.

Figure l is a diagrammatic View showing part of an elevator-hatchway with a car therein and showing my improved means whereby the signal within the car is controlled. Fig. 2 is an enlarged detail view, inside elevation,

of the magnets and mercury-pots whereby the passage of current to the controllingmagnets within the hatchway of the elevator 3o is determined. Fig; 3 is aplan view of the part shown in Fig. 2. Fig. 4 is a face View, and Fig. a view in central vertical section, through a form of circ uit-controllers that are placed in the hatchway and on the car. Fig.

G is a plan View, and Fig. 7 is a view in section, through a form of magnet that is used in both the hatchway and in the car. Fig. 8 is aside view, and Fig. 9 is a face View, of a form of circuit-controller that is used in the 4o circuit wherein the floor-lanterns are placed. Fig. l0 is a diagrammatic View showing an elevator-hatchway and car, illustrating the means for automatically operating the switch within the car. Fig. ll is an end View, and

Fig. l2 a plan view, of the automatic switch within the car. Fig. 13 is a diagrammatic view showing the invention as provided with Ineans forconirolling the lighting of lanterns upon the floors of the building.

In the diagrammatic view Fig. l of the drawings I have shown the mechanism appertaining to a single door of the building, since it will be understood that corresponding mechanism will be used upon all the floors.

A designates the hatchway through which will pass the elevatorcar A', it being under stood, of course, that this car will be furnished with any suitablev mechanism for operating the same and will be furnished with a suitable cable whereby the electric wires a and a will 6o be led to the car from a rotary transformer or other source of current. At a convenient point, preferably adjacent each of the doors of the building, is placed the mechanism illustrated diagrammatically atthe left-hand side of Fig. l of the drawings. This mechanism is shown as comprisingI two pairs of magnets, one pair serving to control the signaling of the car by an intending passenger desiring to ascend and the other pair serving to control 7o the signaling of the car by an intending passenger desiring down service. The magnets b and cof the up signal controlling mechanism, and which are hereinafter termed the releasing and restoring magnets, are mounted upon aframe B, that is carried by an insulating-block C. At one side of the magnet b extends an arm b, to the end of which is pivoted an armature-lever b2, (see Fig. 2,) the bent end of this lever being, pref- 8o erably, furnished with a set-screw b3 to limit the throw of the leve'r. At one side of the magnet c extends the upper arm c' of the frame B, to which is pivotally-connected an armature-lever c2, that normally extends beneath and is held by the armature-lever h2 of the releasing-magnet Z9. The outer end of the armature-lever c2 is preferably furnished with a set-screw that engages a stop to limit its downward movement, and the extreme 9o end of this armature-lever has connected therewith a rod or wire c3, adapted to dip into the mercury-pot D when the rear end of the armaturelever c2 is released from engagement with the end of the armature-lever b2. The frame B' of the down signal controlling mechanism carries twov magnets h and c, corresponding with the magnets b and c abovedescribed,the magnetbhavingan armature-lever ZJ? pivoted adjacent thereto, while the magnet chas an armature-lever c7,that carries at its outerend a rod cs, adapted to dip into the mercury-pot D At a convenient point adjacent'the eleVator-hatchway are placed two push-buttons E and E, the push-button E serving for up signaling service and the push-button E serving for down signaling service. These push-buttons are of any ordinary or suitable type, being normally open. One contact-point of the push-button E is connected by a branch c with a wire 2, that leads to the main feed-Wire 3to which current is delivered from a source of supply connected at its end X. A branch e' from the wire 2 connects one terminal of the down7 pushbutton E With the main feed-Wire 3. From the opposite contact-pointof the up push-buttonEaWireeZleadstothc magnetbo"tl1eup7 signal controlling mechanism, and from the corresponding contact-point of the down push-button E' a wire e3 leads to the magnet b of the down signal controlling mechanism. It will be seen that the signal-controlling mechanism connected with the up push button and that connected with the down push-button are identical. From the magnet Z) of the up signal controlling mechanism, for example, a wire f leads to a Wire f', that connects with a branch Wire Il, that leads tothe main feed return-Wire 5, the free end Y of which wire Will be connected With a rotary transformer or other suitable source of supply at a convenient point. A branch f2 vfrom the wire f leads to the magnet c, and :from this magnet c a wire g leads to a circuit-controller G, located in the hatch- Way opposite the floor corresponding,r to the circuit-controlling mechanism with which it is connected. From the circuit-controller G a wire g leads to the main feed-Wire The Wire g is connected by a Wire g2 to a signalcircuit controller G, that is connected by a Wire g3 with the magnet c6 of the down signal controlling mechanism, and it will be seen thatthe magnets Uand cof the down signal controlling mechanism are connected by branch Wires f4 and f5, that are connected by a branch Wire f6 to the wire 4, that unites With the return-Wire 5. From the mercurypot D leads a wire d2 to a controlling-magnet H, that is located in the hatchway about or at slight distance below the level of the door of the corresponding sign al-conlrolling mechanism, and this controlling-magnet H is connected by a Wire d3 with a signal-controlling magnet H', that is connected by a Wire d4 with the return-wire 5. From the meren ry-pot D of the down signalcontrolling mechanism leads a Wire d5 to a controlling-magnetH?, that is connected by a Wire d with a similar controlling-magnet H3, from which magnet a Wire Z7 leads to the main return feed-Wire 5. From the branch wire 2, that connects with the main feed-Wire 3, a branch Wire b5 leads to the frame B of the up signal controlling mechanism, and from the branch Wire 2 a branch wire b9 leads to the frame B of the down signal controlling mechanism.

From the foregoing description it Will be seen that when an intending passenger desiring to go upward presses the push-button E the circuit will be closed at such point. Current will then pass from the source 0f supply by main feed-Wire 3 and branch Wire 2 and wire e to push-button E, thence by wire c2 to magnet l). From magnet b current Will pass by Wiresff and l to feed-Wire 5 and back to source of supply. The magnet l) being thus energized will attract the armature b2 and Withdraw it from engagement With the rear end of armature c2, thereby permitting the Wire c3 at the outer end of the armature c2 to drop into mercury-pot D and close the circuit at such point. Current will then pass from main feed-Wire 3 by wire 2, by Wire b5 to frame B, to armature-lever c2, to Wire c3, to mercury-pot D, and thence by Wire d2 through controlling-magnet H, by Wire d3 through controlling-magmet H, and by Wire dl to main feed-wire 5, and thence back to source of supply. The controlling-magnets H and H will thus be energized and will so remain until they have performed the function of operating the signal Within the car in manner to be presently described and until the restoring mechanism to be presently described serves to return the signal-controlling mechanism at the door to its normal condition. ln like manner it will be seen that if an intending passenger operates the push-button E the circuit at such point will be closed and current will pass from main feed-Wire 3 by wires 2 and e to the push-button E, thence by wire c3 to magnet b of the down signal controlling mechanism, thence by Wires f4 and f6 and el to the main return feed-Wire 5, and by this Wire back to the source of supply. The eiifect of this passage of current through the magnet t will be to attract its armature-lever b?, thereby releasing the armature-lever c7 and permitting its Wire G8 to Idrop into the mercury-pot D, thus closing the circuit atsuch point. Current Will then pass from main feed-Wire 3 through branch Wire 2 and Wire b9 to the frame B of the downsignalcontrollingmechanism. From frame B current will by armature-lever c7 and rod cS to mercury-pot D', and from mercury-pot D current will pass by Wire d5 to controlling-magnet H2, thence by wire d6 to controlling-magnet H3, and thence by Wire dT and main return feed-Wire 5 to source of supply. The controlling-magnets H2 and H3 will be thus energized by passage of current therethrough until by mechanism to be hereinafter described the down signal controlling meehanism is restored to its normal condition.

At a convenient point upon or within the car is placed the mechanism next to be described Whereby the passage of current through the car-signal, preferably an incan- IOO IIO

descent lamp J, is determined and whereby also the passageof current throughthe restoring-magnets of the up and down signal controlling mechanism at the floors is determined.

Y The feed-wire a leads directly to the lamp J, and with the feed-wire a connects a wire a2, that is connected by one branch a3 with a circuit-controller K and by a branch a4 with a circuit-controller K' and by a branch a5 with a circuit-controller K2 and bya branch a6 with a circuit-controller K3, The construction of each of the circuit-controllers K K', dac., is preferably that illustrated in Figs. 4 and 5 of the drawings-that is to say,.within a suitable casing 7c there is held upon an insulating-block 7s' aplate-spring k2, having attached thereto a soft-iron armature k3, and with the spring k2 will be connected the branch wire a3, (or a4, a5, or a6.) Adjacent the armature k3 and xed to the casing 7n is a contact-plate 7.34, to which will be connected a leading-out wire 7c5, (or 7c", 7.97, or 7c3) that leads to one of the contact-points of the controlling-switch I. In like manner a wire 756 will lead out from the circuit-controller K' to a contactpoint t" of the switch I, and in like manner also -a wire k7 will lead out from the circuitcontroller K2 to the contact-point 2 of this switch. So, also, a wire ks will connect the contact-plate of the circuit-controller K3 with the contact-point s of the switch I. The switch I is of familiar form, comprising a series of pivoted arms connected by an insulated handle-bar, the free ends of these arms being so arranged as to connect their pivotal points with either of two diiferent contactpoints. From the pivoted ends of the arms of the switch I lead wires m, m', and m2, the wire m connecting directly with the returnwire c.' and connecting by a branch wire m3 with the frame M of a circuit controlling mechanism similar to that hereinbefore described, and illustrated in Figs. 2 and 3 of the drawings. The frame M carries the magnets N and N', and this frame is mounted upon an insulating-block N2, that supports the mercury-pot N3. At the side of the magnet N extends an arm n, carryinga pivoted armature n', similar in construction and arrangement to the armature b2, hereinbefore described. So, also, the upturned end of the frame M, that extends adjacent the magnet N', carries an armature-lever n2, similar to the armaturelever c2, hereinbefore described, and this armature-lever n2 has attached thereto a rod n3,

and N are connected by the wires p and p', respectively, to the wire p2, that leads to the frame M. From the wire a2 (that extends from the leading-in wire c) a branch wire S leads to a transfer-button 0 from which button a wire 9 connects by branch wires l() and ll with the controlling-magnets and I-I6 on the car. The controlling-magnet H5 is connected by a wire l2 with a contact-point t8 of the switch I, and the controlling-magnet II6 is connected by a wire 13 with the contactpoint tu of the switch I.

From the foregoing description the operation will be seen to be as follows, assuming the parts to be in the position shown by Fig. l of the drawings, at which time the car is above the fioor at which a down signal has been given. It has already been shown that when the down push-button E' is operated the rod o8 will be caused to drop into the mercury-pot D' of the down signal controlling mechanism, thereby closing the circuit at such point and causing the passage of current through the controlling-magnets H2 and H3. Now when upon the downward movement of the car the circuit-controller K comes opposite the controlling-magnet H3 the soft-iron armature 7c3 (see Fig. 5) of this circuit controller K will be attracted by the magnetic force of the controlling-magnet H3 until this armature 7a3 bears against the contact-plate 7a4, thereby closing the circuit at such point. The result of this closing of the circuit-controller K will be to cause the lighting of the signal-lamp within the car by passage of current in the following manner, viz: From the main feed-wire ct current will pass to branch wire a2 and branch wire a3 to circuit-controller K, thence by wire h5 to contactpoint c, thence through switch I by wire m' to releasingmagnet N, thence by wires p and p2 to supporting-frame M, thence by wire m3 to return feed-wire a'. rent thus passing through magnet N will energize this magnet, thereby attracting its armature-lever n', so as to cause Vit to release the armature-lever n2 and permit the rod n3 to drop into the mercury-pot N3 and complete the circuit at such point. The circuit being thus completed at the mercury-pot, current will pass through the electric lamp J as follows, viz: By leading-in wire a the current will pass from source of supply to lamp J, thence by wire 7 to the mercury-pot N3, by rod n.3 to the armature-lever n2, to frame M, and thence by wire m3 and return feed-wire ct' back to source of supply. The lamp J being thus lighted will continue to burn during the down movement of the car for the purpose of signaling the operator until the circuit in which the lamp is placed is broken in the following manner, it being understood that as soon as the circuit-controller K has passed beyond the inuence of the controllingmagnet H3 the passage of current through the magnet N is interrupted, viz: When the circuit-controller K' passes to a point opposite the controlling-magnet H2, the armature 7c3 (see Fig. 5) of the circuit-controller K' is attracted against the contact-plate 7a4, and pas- The cnr- IOO IIO

sage of current is established in the following manner through ythe magnet N' for the purpose of lifting the rod n3 out of the mercurypot N3 and breaking the lamp-circuit atsuch point, viz: From leading-in wire a current passes by wire c2, branch wire ai to circuitcontroller K', thence by wire k6 to contactpointi" ofswitch Lthence by wire m2 to magnet N', thence by wires p' and p2 to frame M, and thence by wire m3 and return feed-wire d' to source of supply. The passage of current through the restoring-magnet N', thus attracting the armature-lever n2, lifts the rod nsfrom out the mercury-pot Nand breaks the circuit by which current is delivered to the lamp J. As the car-continues to pass downward after the signal-lamp therein has been extinguished the controlling-magnet H5y on the car will come opposite the circuit-controller G' in the hatchway, and the armature Kof this circuitcontroller G', being attracted against its contact-plate 7a4, the circuit will be closed at such point. Current will then be caused to pass through the restoring-magnet c6 as follows, viz: from the rotary transformer or other source of supply by main feed-wire 3 and branch feed-wire g2 to circuit-controller G', thence by wire g3 to restoring-magnet c6, thence by wires f5 and f6 to wire 4, thence by return feed-wire 5 to rotary transformer or like source of current. TheV effect of this passage of current through the magnet c6 is to attract the armature-lever c7, thereby lifting the rod cS out of the mercury-pot D' and breaking the current through the controllingmagnets H2 and H3. It will be understood, of course, that when the restoring-magnet ci is thus energized and the armature-lever c7 attracted thereby this lever will be caught beneath the free end of the armature-lever b7 of the magnet Zi, and it Will be plain also that at the several other points of the system in which a restoring-magnet is used like energization will serve to cause the rengagement of its armature-lever by the armaturelever of the adjacent magnet. When the car reaches the bottom of the shaft or the end of its 1 downward travel, the switch I will be shifted from the position shown by full lines to the position shown by dotted lines in Fig. l of the drawings. This shifting ofthe switch I may be effected manually by the operators moving the knob or handle 'is to the right or maybe effected automatically by the apparatus hereinafter described. It will be understood, however, that while the car is moving in upward direction the switch I will occupy the position shown by dotted lines in the drawings, and when the car reaches the limit of its upward travel the switch will be returned to the position shown by full lines in Fig. l. If it be assumed that the car is moving in upward direction and an intending passenger wishing to go upward presses the up push-button E, the circuit will be closed at such push-button and current will be caused to pass through the releasing-magreagito net b, so as to permit rod- 03 to close the circuit at the mercury-pot D in manner hereinbefore described. The circuit being closed at the mercury-pot D, current will pass to the controlling-magnets H and H' as follows, viz: from main feed-wire 3 by Wires 2 and b5 to frame B, armature-lever c2 and rod c3 to mercury-pot D, thence by wire d2 to controlling-magnet H, thence by wire d3 to controlling-magnet H', and thence by wire d4 to main return feed-wire 5. The controllingmagnets H and H' being thus energized, it will be seen that as the car passes in upward direction from the point below these magnets the circuit-controller K3 will pass in proximity to the controlling-magnet H', and at such time this magnet will attract the armature 763 (see Fig. 5) of this circuit-controller, thereby closing the circuit through such circuit-controller, Current will then pass through the circuit-controller and parts connected therewith as follows,viz: from leading-in wire a by wires a2 and a to circuitcontroller K3, thence by wire S to contactpoint 713, thence by switch I (said switch being in the position shown by dottted lines) and wire m to releasing-magnet N, thence by wires p and p2 to frame M, and thence by wire m3 to the return feed-wire d'. By this means the armature-lever 'n2 will be caused to drop, so as to close the circuit at the mercurypot N3. Current will then be caused to pass through the electric lamp J in the manner hereinbefore described, and the lamp .I will continue to burn until in the upward movement of the car the circuit-controller K2 comes opposite the controlling-magnet H, which magnet by attracting the armature 7c3 of the circuit-controller will close the local circuit at such point. Current will then be caused to pass through the circuit-controller K2 as follows, viz: from leading-in wire a to branch wire a2 and branch a5 to circuit-controller K2, thence by wire 767 to contact-point i2 of switch I, thence by switch I and wire m2 to restoringmagnet N', thence by wires p andp2 to frame M, and thence by wire m13 to leading-out wire d'. The energization of the restoring-magnet N' will return the armature-lever n2 of this magnet to locked position, (shown in Fig. l of the drawings,) thereby breaking the circuit at the mercury-pot N3 and extinguishing the lamp. During the further upward movement of the oar the controlling-magnet H6 thereon will pass opposite the circuit-controller G in the hatchway, thereby closing the circuit through such circuit-controller so as to cause the passage of current through the restoringvmagnet c, and thus return the armature-lever ,c2 to the locked position (seen in Fig. l) and break the circuit through the mercury-pot D.

Instead of operating the switch I on the car manually, as hereinbefore described, this switch may be operated automatically by the mechanism illustrated in Figs. l0, ll, and l2 of the drawings. To this end the contactpoints of the switch will consist of mercury- ICO IIO

pots r, fr', r2, r3, r4, and ri, into which will dip the rods 15, carried, respectively, by the switch-arms 8,3', s2, s3, .94,and 55. These switcharms are fixed upon a rock-shaft S, insulatingsleeve s6 being interposed between the hubs of the switch-arms and the shaft. Against the hubs of the switch-arms s s', dac., bear the corresponding spring-plates S7, ss, and si), that' are connected, respectively, to the wires m, m', and m2, hereinbefore described, and it will be understood that the mercury-pots 0^ r', dac., will correspond with the several contactpoints of the switch shown in Fig. 1 of the drawings,these mercu ry-pots beingconnected with the corresponding wires that lead to such contact-points. The shaft S is mounted in suitable standards 17 and 18, supported upon an insulated base 19, that is suitably supported at a convenient point of the car. The outer projecting end of the rock-shaft S has tiXed thereto a soft-iron armature S', that will be attracted by one or the other of the controlling-magnets T and T', that are shown as located, respectively, at the top and bottom ot' the elevator-hatchway. The controlling-magnets T and T' are the same in construct-ion as the controlling-magnet H, (illustrated in Figs. G and 7 of the drawings,) and these magnets are connected by branch wires t and if' with the return feed-wire 5 of the main circuit and by branch wires t2 and t3 with their respective switches T' and T2, these switches being connected, respectively, with the main leading-in feed-wire 3 by the branch wires t4 and 255. The controlling-magnets T and T' will be so located in the elevator-hatchway that as the car reaches the limit of its upward travel the armature-lever S' Will be attracted by the controlling-magnet T and will be shifted from the position shown in Fig. 11, so as to break the contact at the mercury-pots rr, r', and r2 and establish contact at the mercury-pots r3, r4, and T5. So, also, when the car reaches the limit ot' its downward movement the armature-lever S' will come adjacent to the controlling-magnet T' and will be returned to the position seen in Fig. 11 ofthe drawings, thereby shifting the switch and establishingr contact at the mercury-pots r, r', and r2.

As it sometimes happens, particularly in very tall buildings, that during certain hours of the day an elevator will run only to a certain floor below the upper fioor of the buildin g, while at other hours it will make the complete travel of the hatchway, it may be desired to provide a controlling-magnet T at other floors of the building below the top. lt is for this reason that the switch T' is employed, since when the switch is turned from the closed position (seen in full lines) to the open position (shown by dotted lines in Fig. 10) the controlling-magnet T at any floor can be thrown out ot action. For example, if

during certain hours of the day the car is running, say, tothe fourth floor only the controlling-magnet T will be employed at such door to automaticallyreverse the switch within the car; but if at other hours of the day the car makes the full run of the hatchway the controlling-magnet at the fourth door will be switched out of action.

In some systems of electric signaling apparatus for elevator-cars it is desirable not only that the operator of the car shall receive a signal, but also that lanterns or other signals located at each door shall be brought into operation, so as to indicate to an intending passenger the approach of the next elevator-car coming in the desired direction. When floorlanterns orlike signals are desired, the system of wiring illustrated in Fig. 13 of the drawings will be used. The up signal and down signal controlling mechanism illustrated in Fig. 13 is the same as that hereinbefore described, and with the exceptions hereinafterl noted the wiring is similar. So, also, the controlling-magnets H H', dac., and the circuitcontrollers G and G' are constructed and operated as hereinbefore described. Adjacent the hatchwayof the elevator are located two signals W and W', commonly termed floorlanterns, the signal W serving to indicate to the intending passenger the approach of the elevator-car in upward direction, while the lantern W' serves to indicate the approach ot a car moving in downward direction. The up lantern W is connected by a wire w with the controlling-magnet H, from which a wire d3 leads tothe controlling-magnet H',' this controlling-magnet H' being connected by a wire d10 with a circuit-closer V, that is connected by a wire o with the main return feed-wire 5. In like manner one terminal of the down lantern is connected by a wire w' with the controlling-magnet H3, from which magnet a wire w2 leads to a circuit-closer V', that is connected by a wire o' tothe main return feed-wire 5. The construction of the circuit-closers V and V' is identical and is illustrated in Figs. 8 and 9 of the drawings. Each of these circuit-closets V and V' comprises an electrornagnet v2, that is mounted upon an insulating-block 40, preferably carried by a casing or like support 4l, that will be mounted at a suitable point Within the elevator-shaft. The armature v3 is pivoted, as at 4l, to the bracket 42, this armature being shown as provided with an arm 43, adapted to contact with a set-screw 44, that limits its rearward movement. A soft-iron head c4, attached to the armature o3, serves to hold the contact-point 45 ofthe armature normally away from a contact-point 46 on the soft-iron head 47 of the magnet o2, and the head 47 is connected by a Wire 48 with the coil of the magnet. The opposite end of the magnetcoil o2 in the circuit-closer V is connected to the wire o, and the metal bracket 42 of this circuit-closer is connected to the wire d3. In the case of the circuit-closer V' the Wire that leads from the magnet o2 is connected to the wire to2, while the wire that leads from the bracket 42 is connected to the wire v', that IXO leads to the return feed-wire 5. From the up signal-lantern in a Wire 50 leads to the mercury-pot D of the up signal controlling mechanism, and from the down signal-lantern W' a Wire 51 leads to the controllingmagnet H2, that is connected by a wire d5 (as in the construction before described) with the mercury-pot D' of the down signal controlling mechanism. ln this form of my invention the wires f and f2 of the up signal controlling mechanism are connected by Wires j9 With the frame B, and in like manner the wires f and f5 between the magnets of the down signal controlling mechanism are connected by a vviref10 to the frame B. The frames B and B' are connected by the wires 31 and 30 with the main feed-wire 3. lt will be understood that the circuit-@losers V and V' will be arranged in the elevator-shaft at considerable distancesay the distance of a floor or two-from the ioor at which are located the signal-lanterns W and W' controlled by these circnit-closers, so that an intending passenger will have ample notice of the approach of the elevator-car.

From the foregoing description it will be Seen that when apassengerdesiring up service depresses the up7 push-button E and closes the circuit at such point current will pass from the main feed-wire 3 by Wires 30 and 3l to the frame B, thence by Wires fg andf to the releasing-magnet b, thence by Wire e2 to the push-button E, thence by Wire 54 to the return feed-wire 5. rlhe effect of this passage of current will be to cause the closing of the circuit at the mercury-pot D in manner hereinbefore described. As the elevator-car in its upward travel causes the controlling-magnet H to pass adjacent the circuit-closer V, this magnet Il will attract the armature c3 of the circuit-closer V, causing the contact-points 45 and 46 to come together. Current will then pass through the up signal-lantern W and through the up circuit-closer V as follows, viz: from main feed-Wire 3 by Wires 30 and 3l to the frame B, thence by armature-lever c2 and its rod to mercury-pot D, thence by wire 50 to one terminal of the up signal-lantern W, thence by Wire w to controlling-magnet H, thence by wire d3 to controlling-magnet H', thence by Wire d10 to circuit-closer V, thence through the armature and through the magnet of the circuit-closer to Wire c, and by this wire and the return feed-wire 5 back to source of cu rrent. The up signal-lantern i/V will thus be caused to burn and indicate to the intending passenger that a car is approaching in npward direction. As soon, however, as the carin its upward travel brings the controlling-magnet HG opposite the circuit-controller G current will be caused to pass through the restoring-magnet c in manner hereinbefore described, thereby energizing this magnet and causing the breakage of circuit at the mercury-pot D. The up7 signal-lantern 'W will then cease to burn. ln like manner it yand 54 to return feed-wire 5.

will be seen that when an intending passenger desiring to descend depresses the down push-button E' the circuit will be closed at the mercury-pot D', causing passage of cnrrent from main feed-Wire 3 by wires 30 and 3l to frame B', by Wires fu. and f4 to magnet h6, by wire e to push-button E', by Wires 58 Current will then pass through the down signal-lantern W' as follows, viz: from main feed-Wire 3 by wires 30 and 3l to frame l5', b y armaturelever c7 and its rod to mercury-pot D', by Wire (Z5 to controlling-magnet H2, by wire 5l to one terminal of down signal-lantern W', by wire w' to controlling-magnet H3, by wire 102 to circuit-closer V', and from this circuitcloser by wire e' to main return feed-wire 5. When the car in its downward travel causes this controlling-magnet H5 to pass opposite the armature of the circuit-closer V', the circuit at such circuit-closer will be completed and current `vill then pass through the down7 signal-lantern t l', causing this 1antern to burn and to indicate to the intending passenger the down approach of the car. As soon, however, as the car in its downward movement brings its controlling-magnet H5 opposite the circuit closer G' the circuit at such circuit closer will be completed and current will be caused to pass in manner hereinbefore described through the restoringmagnet c of the down signal controlling mechanism, thereby causing the circuit to be broken at the mercury-pot D. When the circuit is thus broken at the mercury-pot D', the down signal floor lantern W' will cease to burn.

It will be understood that when my in vention is employed upon elevators that are arranged in a bank or series the up and down signal controlling mechanism at the several floors of the building will actuate the signal within all the cars of the series. As it frequently happens that a car first to approach a landing at which a signal has been given is too crowded to receive an intending passenger, it is desirable that provision be made so that the signal given by the passenger shall stand in the next approaching car. For this reason each car is provided with a transferbutton O, that consists of a simple normally closed switch or push-button interposed in the circuit by which current is delivered to the controlling-magnets H5 and H6 on the car. New as these controlling-magnets serve to restore the up and down signaling mechanism at each door to normal condition it is manifest that if the push-button O be opened by the operator as the car passes the floor at which the signal has been given the controlling-magnets H5 and Hwill be inactive, and therefore will not affect the circuit-controllers of the up and down signal controlling mechanism ,and consequently said signalcontrolling mechanism will still continue to operate the signals Within the other cars of the series.
